How to prevent duplicat content issue and indexing sub domain [ CDN sub domain]?
-
Hello!
I wish to use CDN server to optimize my page loading time ( MaxCDN). I have to use a custom CDN sub domain to use these services. If I added a sub domain, then my blog has two URL (http://www.example.com and http://cdn.example.com) for the same content. I have more than 450 blog posts.
I think it will cause duplicate content issues.
In this situation, what is the best method (rel=canonical or no-indexing) to prevent duplicate content issue and prevent indexing sub domain? And take the optimum service of the CDN.
Thanks!

There's no way to reverse proxy and hide that sub-domain? Ideally, a CDN for content itself would never be seen by the crawlers. If people are going to actually see this sub-domain and potentially link to it, then you're probably going to have to use cross-domain canonical. That's not an ideal solution, though - ideally, the CDN should be invisible to Google and visitors.

Hi Godad,
If it was me I would go for the canonical version.
if you want to go with the no-index, then do not forget to use no-index, follow (so you do not miss the "link juice" those pages might get).
I hope it helped,
Istvan

Sub Domain Redirect
Hey Everyone, Here is the situation : Currently, a website's sub domain is being redirected to the main website home page. We're having issues getting the sub domain pages indexed. Just want to confirm that it is because of the redirect on the sub domain URL. Should we kill the sub domain redirect and set it up as it's own page? Will that solve the indexing issue for the sub domain pages. More explanation below: subdomain.domain.com currently redirects to domain.com We're having issues indexing pages belonging to the sub domain ( subdomain.url.com/page1 or subdomain.url.com/page2) Appreciate your input in advance. Cheers,

Google Webmaster tools Sitemap submitted vs indexed vs Index Status
I'm having an odd error I'm trying to diagnose. Our Index Status is growing and is now up to 1,115. However when I look at Sitemaps we have 763 submitted but only 134 indexed. The submitted and indexed were virtually the same around 750 until 15 days ago when the indexed dipped dramatically. Additionally when I look under HTML improvements I only find 3 duplicate pages, and I ran screaming frog on the site and got similar results, low duplicates. Our actual content should be around 950 pages counting all the category pages. What's going on here?

Content on top-level-domain vs. content on subpage
Hello Seomoz community, I just built a new website, mainly for a single affiliate programm and it ranks really well at google. Unfortunately the merchant doesn’t like the name of my domain, that’s why I was thrown out of the affiliate program. So suppose the merchant is a computer monitor manufacturer and his name is “Digit”. The name of my domain is something like monitorsdigital.com at the moment. (It’s just an example, I don’t own this URL). The structure of my website is: 1 homepage with much content on it + a blog. The last 5 blog entries are displayed on the homepage. Because I got kicked out of the affiliate program I want to permanent redirect monitorsdigital.com to another domain. But what should the new website look like? I have two possibilities: Copy the whole monitorsdigital website to a new domain, called something like supermonitors.com. Integrate the monitorsdigital website into my existing website about different monitor manufacturers. E.g.: allmonitors.com/digit-monitors.html (that url is permitted by the merchant) What do you think is the better way? I just got the impression, that it seems to be a little easier to rank high with a top-level-domain (www.supermonitors.com) than with a subpage (www.allmonitors.com/digit-monitors.html). However the subpage can benefit from the domain authority, that was generated by other subpages. Thanks for your help and best regards MGMT

To 301 redirect or not to 301 redirect? duplicate content problem www.domain.com and www.domain.com/en/
Hello, If your website is getting flagged for duplicate content from your main domain www.domain.com and your multilingual english domain www.domain.com/en/ is it wise to 301 redirect the english multilingual website to the main site? Please advise. We've recently installed the joomish component to one of our joomla websites in an effort to streamline a spanish translation of the website. The translation was a success and the new spanish webpages were indexed but unfortunately one of the web developers enabled the english part of the component and some english webpages were also indexed under the multilingual english domain www.domain.com/en/ and that flagged us for duplicate content. I added a 301 redirect to redirect all visitors from the www.domain/en/ webpages to the main www.domain.com/ webpages. But is that the proper way of handling this problem? Please advise.

Can I do a redirect to a new domain name only a couple of weeks after having redirected to another domain?
I have a client with two website with very similar content. Both had a lot of inbound links and performed fairly well in SERPS. We recently combined both sites and have redirected one of the domains to the other. The traffic dipped slightly initially, but is recovering nicely. Now the client registered a new domain name he would like to use for the site. Should I wait a few weeks for everything to settle down after the first redirect/consolidation of sites before doing a new redirect to a new domain name, or should I not worry about having any issues with doing it right away?

Hi, I like to do something, but first like to take some opinions from seomoz. My question is: 1. I have a domain: brandtrends.com and i like to move this from brandtrends.com to trends.brand.com because: brandtrends.com is on the position #15 on the second page of SERP for my "brand" keyword. I like to move it under trends.brand.com but all inbound-links are @brandtrends.com What do you thing, if i move permanently 301 from brandtrends.com to trends.brand.com does it rank under brand.com on the 1st page of SERP..? like to rank trends.brand.com under brand.com on results page...!!! I have the backlinks of brandtrends.com on my hands too, should i leave the inbound links @brandtrends.com and the new ones i build with trends.brand.com or should i change the inbound links from brandtrends.com to trends.brand.com Hope you got it! THanks

Do search engines still index/crawl private content?
If you have a membership site, which requires a payment to access specific content/images/videos, do search engines still use that content as a ranking/domain authority factor? Is it worth optimizing these "private" pages for SEO?
